RECORDER.

Specification of To all atom it may concern Be it known that we, IIARRYT Goss and JAMES \V. Bnrcn, citizens of the United States, and residentsof Rutherford, county of Bergen, and State of New Jersey. have inventednew and useful Improvements in Recorders, of'which the following is aspecification.

Our invention relates to recorders.

It is of special value in connection with time recorders andparticularly in connection with indicating elapsed times, as for examplethe elapsed time between the starting of work on a particular job andthe stopping of work'thereon. ,It is however not limited to such uses;nor is it limited-to indicating difierences in time, as it may be usedfor indicating other differences, as for example, in money values.

Our invention is illustrated in the drawings, accompanying thisspecification and forming a part thereof, in connection with .a machinefor indicating elapsed times between the starting and finishing of work,by an operator, on a job or of a days work of the operator, although ofcourse it is not limitedto use in such a machine. The form of indicationmade in the particular machine shown in the drawings is printing theelapsed time in hours and minutes upon a card inserted by the operatorin a suitable receptacle in the machine Any other suit" able method orform of indication may'howclock movement; devices, as shown one forthe'hours and one forthe minutes, cooperating w1th and controlled bythestarting time markson theca'rd, when inserted later Application filedAugust 30, 1905.

The result isthe printing upon the card of the time that has elapsed between theinsertion-by the operator of the card in the starting time receptacleand its insert-ion later on in the elapsed time receptacle. greaterdetail, the clock movement by means of suitable gearin positions certaincams, and these act as stops to stop the rotation of the elapsed timetype wheels.

Slots, preferably two in number, are provided in the face of the device,labeled Starting time and Elapsed time, respectively. When it is desiredto obtain a record of elapsed time, a card-of the correct size isinserted by the operator in the slot pulled down and a record is therebyobtained of the time of such operation. In the form of device about tobedescribed, this record takes the form 'of two holes punched near theedge of the card and opposite apair of scales previously printed at.

trolled by the clock. The punches are then 'this arrangement we obtain adevice which has no drop bit (2'. e. no return to zero at somepredetermined hour during the day), as would be the case were thepunches fed forward and returned directly by the clock itself. Ve alsokeep the load of driving the mechanism off of the clock and put it onthe handle from which ample power is more readily obtained. The handlein the machine. shown thus constitutes the means for operating theelapsed time indicating mechanism.

As the apparatus shown is designed, there is nothing to be driven by theclock but a pair of cams which are preferably built in the form of disksand are therefore bal anced.

Vhen it is desired to obtain a record of elapsed time 2'. e. the timethat has expired since the punching of the card, the said card isinserted by the operator in the slot marked Elapsed time and the samehandle is pulled down as before. In this case a pair of selectingfingers traverse the card from left to right and spring into the holespreviously punched. This immediately causes the type wheels to startturning about their axes. The holes previously punched in the card, thusconstitute starting time identifying marks placed on the card and theselecting fingers constitute devices adapted to cooperate with the saidmarks on the card. which thus control them for the purpose of startingthe elapsed time indicating mechanism into operation. The type wheelscontinue to turn until stopped by the beforementioned cams operated bythe clock. This of course, occurs before the type wheels have quitecompleted a revolution. An instant later the hammers are tripped oif bythe handle and an impression of the characters on the type wheelsstanding opposite the card is made on its face. in a blank spaceprovided. for the purpose. If, however, the card is not inserted deepenough into the slot. or no card at all is inserted, the hammers do notact as the trip of]? is put out of engagement by a finger provided. forthis purpose. This finger travels upward with the movement of the handleand if arrested in its travelby the presence of a card. does notinterfere with the trip which is normally in a position to act on thel'aann'ners. If, however, itis allowed to complete its travel, as whenno card is inserted or a card is not inserted far enough, it forces thetrip pawl out of engagement and the hammers remain in their normal oroperative position and no printing is done.

It will be seen that we are thus enabled to print any number ofoverlapping elapsed times and any number of starting times may be takenbefore any elapsed time records are printed and any number of elapsedtime records may be taken in succession. lturt-hermore, it makes nodifference at what time of day or night any record starts as the clockrecords any time up to twenty-four hours, and can be made accurate to aminute. If desired minutes and seconds or hours, minutes and secondscould be printed with suitable modifications.

If any one attempts to make a false record by failing to insert the cardfar enough into the. starting time slot, it will be indicated by theholes not being in register with the scale printed on the card, when ascale is employed. or by the total absence of one or both of the holes.moved endwise in the slot owing to the slot being provided with metalguides.

Referring to the specific-form of our im provement shown in the drawingswe will now proceed to describe the devices there shown and their modeof operation taking them up in the order, as nearly as possible, inwhich the various steps are performed in the operation of the machine.

T/a' dew/( es f0! bring/my t/zc punk/res into /o..\-ifi/'on..-lliesedevices are particularly illustrated in Figs. 1. 5, 6. 8, 13, 11-, andThe operator first inserts his card, a form of which is shown in Fig.22. iii the starting time slot and then pulls down thehandle 5-. Thismoves over the card from left to right two punches, a minute punch andan hour punch. These punches move until they are stopped by cams 'drivenby the clock work 7 of the machine. This causes the hour and minutepunches to he brought into correct position over the card and with theedge of each punch'in line with the marks on the scale representing thehour and minute .when the machine is operated. The continued operationof the handle causes these punches to be forced downward through thepaper making holes in the card which holes represent the time when theoperation takes place, the edge of each hole indicating the hour orminute of the operation as clearly shown in Fig. 22.

These holes constitute starting time identification marks as wlllpresently be shown. Their location on the card is controlled by .theclock movement.

Preferably the minute punch is moved its full movement and then afterthat the hour punch is moved. These movements are caused preferably bythe moven'ient of handle 5 fast on shaft 89. The devices shown formoving the minute punch are as follows: Faston this shaft is a minutecam 66 (Fig. 5). Riding on this is a roller 64 of bellcrank lever 62pivot-ed on a stud 1n the framework at- 72 and carrying at its other enda link 60 secured to the driving sector The latter meshes with a pinion15-1 loose on shaft 155. This pinion 154. is fast to disk 251 (Figs. 11and 15) being secured to a common hub 255 loose on sleeve 250. Disk 251carries a pawl 252 (Fig. 15) provided with a sprin 258, the pawlengaging with a single tooth 256 on disk 254. This disk fast on sleeve250. l ast on the other end of this sleeve is a driving gear 163.Mounted on this gear is driving pawl 160' (Fig. 13) adapted to engagewith an arm 158 of pinion 159 loose on sleeve 250. Driving sector 58turns pinion 154: a full revolution in the downward n'io'vement of thedriving sector. This through disk 251 and pawl 252'gives a completerevolution to disk 254 and thence to gear 163. The return eighty degreesas a maximum and will be rotated a less distance depending upon theposition of the minute disk clock cams '35? (Fig. 13) mounted on thedisk 15? driven by the clock work.

dred and eighty degrees apart. ()ne of these cams is therefore alwayslocated within a half circle and driving pawl 160 rides up upon this camand is freed from arm 158 on pinion 159. Arm 158 and pinion 15S) remainin any position to which they are moved. They are moved against a spring20 shown in Fig. 3. They are held in their set position against thisspring by means of a ratchet wheel 16% and pawl 80 (Fig. 5) mounted onthe side frame of the machine. In this way the position of the minutedisk caln 157 determines the position to which the minute punch is movedover the card.-

fro-1n left to right so that the set position of the punch will indicatethe exact minute when the handle is pulled down. Disk 157, is driven bythe clock work by means presently to be described.

Driving pawl 160 is frictionally held in whatever position it is movedinto. At the completion of the revolution of gear 163 pawl 160 strikes aspring 161 011 the side of the machine and is restored to operativeposition. Spring 161 not only restores pawl 160 to its operativeposition, but also permits the clock cams 257 to rise and pass under it,whenever in their rotation they reach it, whereupon spring 161immediately returns the pawl to its operative position again. I

The hour punch is moved into set position by means of the followingdevices; cam 65 fast on shaft 89 (Fig. 5), roller 63, bellcrank 61pivoted on stud 7 2, link 59, driving sector 57 gearing with. pinion 153loosely mounted on sleeve 250 and fast to disk 174. (Fig.14) whichdrives disk 171 by a spring pressed pawl (not shown) similar to 252.Disk 171 is fast on sleeve 258 carrying gear 167. This gear has mountedon it a pawl (not shown) exactly similar to pawl 160 on gear 163 andthis gear completes a revolution on each operation of the handle exactlyas does gear 163. This pawl operates an arm 168 on a pinion'lTO andpinion 170 engages a sector This sector has a crossover rod 150 fast onarm 144. Arm 168 and Disk 15? is providedw1th two of these cams arrangedone hun- 2 operating in the same way.

pinion 170 have mounted fast withsthem a ratchet wheel 86 similar to 16&having a pawl (not shown) in engagement with it mounted on the same studas pawl 80 and Arm 144 at its lower end has a link 259 connected to hourpunch frame 260 (Fig. 6). The hour cam disk 166 is provided with anddriven by clock work, as will be presently described, and is alsoprovided with two cams (not shown) arranged exactly as are cams 257 ondisk 157. The length of movement of the hour punch frame is determinedby the posit ion of the hour cam on disk 166 in exactly the sameananneras already described for the minute mechanism. The minute punch framecarries a minute punch 261 and the hour punch frame carries a similarpunch 262 which cooperate with dies263.

The minute and hour punch frames are each supported by and move upon arod 114 and a guide llt fast. to the framework of the machine.

After the punches have been brought into the proper position to indicatethe. time the are forced downward through the card so as to punch holespreferably of the form shown in Fig. 22. The means for operating thepunches will now be described.

IHim/ 1.-opcmiing ale vices.-These are par ticularly illustrated inFigs. 3, 6 and 8. As shown they consist of the following dei' Fast onshaft '89 is a crank arm 105. Pivoted to this is a link 106 having aslot 109 at its lower end. Through this slot projects a pin 26% fast tocrank'arm 107- secured to rock shaft 108. T 112, one arm which is 111and the other arm by pivoted to a link means of. a link 110 andbellcrank lever 26.5,pivoted at 266 is secured to a secondfiand to theframework,

Each of these is pivoted similar link 111.

to a block 267 which blocks carry universal bar 116. The universal barextends over the punches the entire distance of the travel of the punchframes. When the handle is pulled downward the mechanism above describedpulls universal bar 116 downward and this forces both of the punchesdown ward and through the paper. On the return or upward movement of bar116 the punchesare carried upward by means of metallic L-shaped pieces11 5 running on each side of the universal bar 116 and arranged to"catch under a projecting partof the punches as shown in Fig. 6. TheseL- shaped pieces lift the punches up with them as the universal barrises pulling thepunches out of the paper and into their normalposition. These parts are returned to their normal position by spring102 (Fig. 8) fastened to the side fran'ic of the machine and a crank arm1.01 fast on shaft 89. These return the handle and'all its connectingparts to their normal position.

ices.

his rock shaft carries bellcrank hour hole.

"lhe parts are then automatically returnt to their original or normalpositlons and the Pawls 80 are normally held outof engagement with theratchet wheels 164 and 86 by means of a wire 79 fast in shaft 268 (Fig.5) which carries the pawls 80. Driving sector '57 in the normal positionof the parts forces -'wire 79 slightly upward lifting the pawls out ofengagement with their ratchet wheels. The first movement of drivingsector 5? permits the pawls to be thrown into operative position. Thereturn of driving sector 57 to its original position again removes thepawls from looking position whereby the ratchet wheels and theirconnecting parts all return to their normal positions under theinfluence-of springs 20, shown in Fig. 3. All of the parts that havebeen operated have now been returned to their normal or originalpositions and the machine is ready for the insertion of another card ineither slot or the'same card in the elapsed time slot.

lVhen the operatorhas completed the job i or the day is ended, heinserts the same card,

that has been previously punched. in the elapsed time slot and againpulls down the handle. This causes selecting fingers to move over thecard from left to right until they spring into .the -lroles previouslypunched in the card. There is a selecting finger for theaninute hole andone for the ie minute selecting finger moves first. When it drops intothe minute hole in the card, a minute type wheel is released and ismoved by devices presently to be described, until it is stopped by aminute cam controlled by the minute gear of the clock work and then thehour selecting finger moves until it drops into the hour hole whenanhour type wheel is released and is moved by suitable mechanism until itis similarly stopped by an hour cam controlled by the hour gear of theclock mechanism. The selecting fingers in the-machine shown thusconstitute devices. cotiperating with and controlled by the startingtime identifi cation marks on the card. for start-ing the elapsed tlmelndicatlng mechanism. The continued operation ofthehandle then actuatesthe printing mechanism causing the number of the hour and minute to beprinted upon the card in the spaces left for them, shown nrFig. 22, Fig.23 illustrates. an instance 111 which such printing has been done.

card is withdrawn by the operator. These devices will now. be'described.

Tim (lat ices for mooin the 'sdccte'n fingers occr Hm curd.-T he devicesfor illustrating the movement of the selecting fingers are especiallyshown in Figs. 1, 5, 6. 7 and 25. i here the number of the minute whenthe operator inserts a card in the elapsed time slot is higher than thenumber of the minute when he inserted the same card in the starting timeslot, the elapsed time in hours will be correctly represented by thetravel of the hour type wheel from proper time to be thrown into"operative position to stop the hour type wheel one,

point or hour sooner than it would be stopped by the regular hour cam.The devices for doing this willbe presently described. For this reasonthe minute selecting' finger and minute type wheel should move first andcomplete their operation before the hour selecting finger and thehourtype wheel are moved in order that the said additional cam stop may,in the proper case, be moved into operative position.

The devices for moving the minute selecting fing'er are as follows: Assector 58 moves downward it rotates shaft 24 upon which it is fast andlifts crank arm 67 pulling upward link attached to crank arm 238 fast onshaft 121. This rotates shaft 121 and causes driving arm 123 to swing upward and to the right causing it to move the minute selecting devicesfrom .left to right across the scale on the card. The

details of this part of the movement are the same as those for movingthe hour selecting finger and as those are shown more in detail theseparts will be described later or in connection with the similar devlcesfor moving the hour selecting finger. The hour selecting finger is movedthrough driving sector 57 a crank arm 68, link 71, crank arm 237,crossover 122, driving arm 124, see Figs. 7 and 25. This driving arm 124has pivoted to its upper end a link 142 secured to a driving block Thisdriving block ismounted to move freely on guide rods 120 secured in theside frames of the. machine.

134 is the'hour selecting finger. It is carried on a driven block 139,similarly mounted on guide rods 1 20. It is removably secured to anddriven by driving block 135 by. means of a hook 269 integral with theselecting;

card. In Fig, 25 the driving block and. driven block, are shown asdisconnected. The driving /block is'always carried to the extreme rightin every operation of the handle. This is true whether a card-isinserted in the slot or not. The driven block .139, however,'remainsunderneath the hole .in the card, as shown in Fig. 25. Exactly similardevices are used between the minute driving arm 123 and the minuteselecting finger 133 (Figs. 3 and 6). Of these 147 is the linkcorresponding with 1 12. Driving block 28gcorresponds to block 135 anddriven block 29 corresponds with block 139.

By means of the above devices the two selecting fingers have beenmovedalong the card until vforced upward into the holes punched into thecard. This starts the type wheels revolving. We will now proceed todescribe such devices.

Type-wheels and their operating devices.- 9 is the minute type wheel and8 the hour type wheel (Figs. 3' and 4t). These'type wheels areconstructed in a similar manner and are driven by similar gearing. The

to move until stopped by the cam mechanism controlled by the clock work.The

.movement of the type wheels is caused by the movement of handle 5. Themechanism for operating these type wheels so that they are moved bymechanism connected with the handle is similar in the two cases. In thecase of the minute wheel 9 its operating mechanism consists of a shaft 11 to which the type wheel 9 and its ratchet 13 are fast, spur gears 17,17, bevel gears 18,18 (Fig.

3), vertical shaft 87 (Fig. 9), beveled gears- 85, 85 sleeve 84:, spurgear 81. Gear 81 is driven through gear 177 shown in Fig.-.14. The meansfor driving this latter gear will presently be described.

The hour wheel 8 and it's ratchet wheel 12 are driven ,by gears 16, 16,(Fig. 3), one of which is secured to its hub, bevel gears 19,

vertical shaft 88. (Fig. 9), bevel gears 21,

shaft 83, spur gear 82. Gear 82, is driven by gear 203 (Fig. 14). Thedevice for driving this gear will be presently described v The drivinggearing just described for rotating the minute and hour type wheels areoperatively connected with the handle and its mechanism only when thecorresponding selecting finger enters a hole in a time card. The devicesfor this purpose will now be described. The figures which show thesedevices'particularly are Figs. 3, 6, 14, 16- 21 and 2;). I The movementof the selecting fingers across the card from left to right until theydrop into their respective holes causes the movement of two cams, onefor the minute mechanism and the other for the hour mechanisnn. hen theselecting fingers are caused each to operate a pawl throwing the pawlinto operative or driving connection one with the minute type wheel andthe other with the hour type wheel. These two type wheels are thenrotated until the pawls above referred to are thrown out of operative ordriving position by disk cams connected with or controlled by the clockwork. This causes the hour and minute type wheels to rotate a distancecorresponding to the elapsed time between the time when the card wasfirst inserted into the machine and the handle operated and the timewhen the same card was inserted into the elapsed time slot and thehandle again operated. The particular devices shown in the drawings forcausing the movement of these selecting fingers to move the cams forthrowing the aforesaid pawls into operative position are as follows:Referring first to the minute.

type wheel mechanism and driving connections, selector arm 130 which hasbeen already described, has been moved through link 1 18 and drivenblock 29 to a certain position depending upon the position of the holepunched in the card by the minute punch. Fast to selector arm 130through crossover rod 128 is a sector 127 (see also Fig. 5) which turnspinion 17(5 fast on sleeve 271,which sleeve is loosepn shaft 175. Faston the other end of the s eeve 271 is an arm 189 and on it is riveted acam 188 having a sloping cam surface on its extreme outer end (see Fig.19). Arm 189 and its cam 188 are moved 180 or some point less thanthatdepending upon the position of the hole punched in the card by theminute punch. When the minute selecting finger drops into the hole inthe card arm 189 and cam 188 are arrested and held. 272 is a sleeveturning looselyon sleeve 2 71. At the and like gear 163 makes a completerevolution at each motion or movement of the handle.

Fast on one side of gear 206 is a plate 185 (Fig. 17) carrying a stud274 upon which is pivoted a pawl 183. This pawl is composed of two parts180 and 181 (Fig. 18) each loosely mounted on stud 27 1. These two partsof the pawl are frictionally held so as to move together egicept asdescribed below. The two parts are held in the position shown in Fig. 18by a spring 184. Pawl' 183cmries a pin 182 projecting sidewise from itsurface on the end of plate 188. As the handle is turned pin 182 on itspawl is 1'0- tated in the direct-ion of the arrow (Figs. 1618) making acomplete revolution at each operation of the handle. Arm 189 with itsplate and cam surface 188 are rotated in a similar direction and at thesame speed so that pin 182 will during this rotation lie upon thesloping cam surface of plate 188. Butwhen arm 189 is arrested, as abovedescribed. by a selector finger entering the punched hole, pin 182 inits further rotation is forced upward on the sloping cam surface 188 andthis tips pawl 183 bringing its'nose or pawl end (shown at the left .inFig. 18) into operative engagement with't-he' teeth of ratchet wheel187. There is one tooth on this ratchet wheel 187 for each tooth of theminute wheel. This starts the rotation of ratchet wheel 187 and throughthe connecting mechanism starts the rotation of the minute type wheel.The ratchet 187 and gearing continues to rotate until stopped .by a camcontrolled by the minute part of the clock movement. The devices usedfor these purposes are as follows: 178 is a gear which is driven fromthe minute part of the clock movement. This gear is fast on the hub 275loose on sleeve 272 and on the same hub is securely mounted a disk cam186 carrying two project-ing cam surfaces 276. As pawl 183 rotates pin179 will in the course of its movement through 180 or less, strike oneof the cam surfaces 276. This will throw the pawl so that it is outofconnec-.

tion with the ratchet wheel 187. This will cause the minute type wheelto stop rotating. The pawl and its connecting parts will then continueand complete their rotation but the type wheel will remain in theposition in which it has been stopped with the type representing theminutes of elapsed time bepween the two operations upon the printing Itwill be noted that the sloping cam surface of plate 188 throws pawl 183into; operative position and. the effect of the cam surface 276 of camdisk 186 is to throw the pawl out of operative position. It is pos siblethat both of these cam surfaces, namely, 188 and 276, may strike pins182 and 179 respectively at the same moment. For this reason and inorder to prevent blocking of the machine it is necessary to make pawl183 of two parts that are movable relatively to each other when pins 182'and 179 are struck by their cam surfaces at the same moment. pins to beforced upward at the same time in which case a zero would be printed. Inorder to insure, under these circumstances, that awl 183 is disen agedfrom ratchet whee 187 the cam surface of cams 276 is made somewhatlonger than the operative and lying .normally on the sloping cam I camsurface of plate 188 so that cam surface Spring 184 permits both ofthese i with the type of the minute wheel.

In the particular form of construction shown in the drawings theselecting devices will be moved upward immediately upon the beginning oftheir movement, sl ould there be no card inserted in the slot. Thiswould, of course, cause pawl 183 to engage at once with ratchet wheel1'87 and would move the type wheel until arrested by a cam 276 in themanner already described. In order to guard against the printing of typewe have arranged the printing mechanism so that it is not operativeunless a card is inserted. In the case above cited, therefore, while thetype Wheels will be turned there will be no printing done.

In the 'formof construction shown in the drawings should a card beinserted without having had a hole previously punched in it.

pawl 188 at the end of a movement of 180 would be thrown into operativeposition by pin 182 riding up on sloping cam surface of 188 inasmuch asthe pawl completes a full revolution at each operation ofv the handlewhile arm 189 and its cam 188 only move 180 and there stop. In order toguard against this contingency we provide a projecting surface 277 onratchet wheel 187. The nose of pawl 183 will lie opposite this surfaceat the expiration of a movement of 180. Accordingly as pin 182 is forcedupward'it will simplystretch spring 184 without moving pawl 183 intooperative position. Accordingly that-pawl will remain in its outward orinoperative position all ready for the next operation.

The devices for moving the hour type. wheel are substantially identicalwith those already described for moving the minute type wheel. Theyconsistof the following: These parts are actuated from selector arm 129already described. This arm is fast on shaft 125, at the other end issector 12(i"en gaging pinion 202 fast on a sleeve 278 loose on hub 279.Fast to the other en dof sleeve 278 is arm 200 (corresponding to arm189) and carrying cam plate 201. On'sleeve 279 loose on shaft 175 isgear 203 meshing with pinion 82 (Fig. 9) which drives the hour typewheel as already described. On the inner end of hub 279 is the hour typewheel ratchet 193 (see Fig. 21) corresponding with minute type wheelratchet 187. Lying next to the ratchet wheel is gear wheel 289 in en-.gagement with gear 167 (corresponding with minute gear 108). Mounted on,that gear is plate 196-(corresponding with 185). This plate carries astud ,280 upon which are mounted the two parts 197 and 198 of'a pawl 208which is provided with pins 195 and 199 (corresponding with pins 179 and182) and has a spring 205. Up to this point the devices for impartingmovement to the hour wheel to represent the elapsed hours in time areexactly similar to those operating the minute type wheel. Vere thenumber of the minute of the time of insertion of the card into theelapsed time slot always larger than the number of the minute of theinsertion of the card in the starting time slot, there would be nodifference between the devices for operating the hour type wheel andthose of the minute type wheel. But whenever the number of the minute ofthe time when the card is inserted in the elapsed time slot is less thanthat of the number of the minute -when itwas inserted in the startingtime slot, it is, as is evident, necessary to subtract one from thenumber of hours. F or this reason it is necessary to make the construction of the parts of'the devices for operating the hour type wheelsomewhat different from that of the corresponding parts for operatingthe minute type wheel, in order, in the case indicated, to make thelength of travel of-the hour type wheel one point less than it otherwisewould be. This may be accomplished in any suitable manner. In the formshown in the drawings we accomplish it by means of the followingdevices: 191 (Fig. 20) is a ring gear corresponding to the minute gear178. It meshes with gear 105 (Fig. 14-.) which is in train with the hourmechanism of the clock. A cam disk accompanics the ring gear 194 andsupports it and fast to it is a plain disk 281, which is fast on hub 282and rotates. loosely on shaft 175 and has cams 219 (Figf20'). These camsare exactly like cams 276 andoperate in a similarmanner. Loosely mountedon disk 281 are two subtractor cams 220 loosely mounted on pins 221;These subtractor. cams are arranged immediately in front of the cams 219and situated one point-in front of them. Normally the subtractor. camsare out of operative positi0n,.as shown in Fig.

20. In this position they will not strike pin 195, one of the cams 219in that case striking pin 195 when it reaches it. The tail of eachsubtractor cam is provided with a pin 283 adapted to move in-slot284formed in an i in fast to ratchets 191 and 190, having teeth pointing inopposite directions. Pawls 209 and 210 are adapted to engage withratchets 190 and 191 respectively. Of course it will be understood thatarms 192 and their two ratchet disks rotate with the gear 191. Pawls 209and 210 are for the purpose of moving arm 192 to the left-or rightrelatively to gear 191so as to raise or depress the cam end of cam 220and put it into or out of operative position. A spring 218 tendsnormally to hold pawl 210 against stop 217 and in engagement withratchet punched hole in the card moves past the point 222 of lever 212(Fig. while still in its down position, it strikes cam surface 222pushing it outward and rocking lever 212. It will be noted that pawl 183will be in its down position at this point, unless it has encountered aminute cam between the time the -selecting finger has dropped into, thepunched hole andthe expiration of the minute in which this has takenplace. In that case it is necessary to subtract one from the hours thatwould otherwise be represented by the movement of the heur wheel and beprinted upon the card. Should pawl 183, however, be in its up positionin passing point 222 of lever 212 its cam surface 207 will not engagewith point 222. When cam surface 207 does engage with surface 222 lever212 is rocked on its stud 213. 210 is a lever loosely mounted on stud213 and connected by a spring 285 with lever Lever 210 carries on itsupper end pawl 209. When cam surface 207 rocks lever 212 spring285throws lever 210 and pawl to the left, as

I viewed in Fig. 20, bringing pawl 209 into operative engagement withratchet 190. The spring 285 is to permit pawl 209 to give if necessary.The effect of this operation is to throw cams. 220 into operativeposition a oint in front of ca-ms 219. One of the cams 220 will thenstrike p n 195 instead of one of the cams 219 striking it. This willarrest the movement of the hour type wheel one' point or hon-r soonerthan it would have been arrested had cams 220 not been thrown intooperative position. In this way one is subtracted from the movement ofthe hour wheel. Pin 211 fast to the framework pulls j pawl 209 out ofoperative engagement with ratchet 190 when lever 210 is in its downposition. The tail of pawl 209 is so shaped as to coiiperate with pin211 to this end. Spring 286 secured to lever 210 and to stud 211normally hold the parts in the positions shown in Figs. 18 and 20.

Cams 220 are returned to their normal inoperative position'at the closeof the oper .ation of the machine through pawl 216 (normally out ofengagement as shown in Fig. 20). This-is accomplished through a rockshaft 214, operated through mechanism connected with the operatinghandle, as'will be 'n'esei'itly described. At the close of the operationit is rotated in the direcclock slightly lifting lever 215 fast to theshaft. Pawl 216 is pivoted to this lever and tends to move to the rightthrough the operation of spring 218. Pin 217 fast to the frameworknormally holds pawl 216 out of engagement. \Vhen the pawl is raisedthrough the movement of the rock shaft and the-arm 215 a cut-awayportion 287 in the pawl 216 permits the pawl to move inward intoengagement with ratchet 191 and the upward movement moves ratchet wheeland arm 192 so as to bring the cams 220 into their inoperative positionready for the next operation.

The hour and -minute type wheels have now been moved so as to bring uponthe printing line the hour and minute representing the elapsed timebetween the time when the card was inserted in the starting time slotand the handle operated and the time when it was subsequently insertedinto the elapsed time slot and the handle again operated. For purposesof illustration Fig. 22 represents the time when the card was in sertedin the starting time slot and the handle operated, namely, 7.19 a. m.The clock in Fig. 1 represents the time when the card was inserted inthe clasped time slot and the handle operated, namely, 10.06 a. m. Thelapsed time in this instance is two hours and fortyseven minutes and Frepresents this time as printed on the time card. In this instance itwill be noted that the subs tractor cams were used. In this illustrationthe hour cam at the time when the elapsed time was taken was of coursestanding at ten oclock and the hour cam when the start-- ing time wastaken stood at 7 ocloek. If it had not been for the subtracting featurethe time printed would have been three hours instead of two. I

The numbers standing on the printing line on the hour and minute typewheels are next printed upon the card in the spaces left for them, asshown in Figs. 22 and 23. The mechanism for effecting this printing willnow be described.

Printing mecham'sm.-These are especially illustrated in Figs. 3, 8, 10,11 and 12. 99 is a cam fast on shaft 89 (see Fig. 10). When handle 5 ispulled downward shaft- 89 and cam 99 rotate in the direction of thearrow shown in Fig. 10. After handle 5 has moved downward for someconsiderable distance cam 99 in the ordinary operation of the machinewill strike the curved surface of rock lever 98 pivoted on stud 101secured to the framework. 97 is the other end of the bell-crank lever98. Loosely pivoted on this lever is a tripping pawl 94 normally heldbyspring'96in the position shown in Fig. 10 with its nose over finger93, fast on shaft 92. 92 carries the hammer arms and hammers 288,secured to an ordinary knee tion of the movement of the hands of a joint236 on rock lever 235 fast on shaft 92'.

hammer arms downward. The lower end of' trip 94 moves downward nearly ina vertical line and soon strikes a sleeve 289 loose on shaft 89. Thiscauses trip 94 to disengage from finger 93 whereupon the hammer arms arethrown rapidly upward by spring 103 fast on arm 290 secured to shaft 92and secured at the other end to the framework of the machine. Thiscauses a sudden blow to be given effecting the printing in a legiblemanner. The return movement of shaft 92 and lever 285 is arrested by thelatter striking the casing of the machine. This is the ordinaryoperation of the printing mechanism when a card has been duly insertedinthe elapsed time slot. In case, however, a card has not beenintroduced at all it is desirable that the printing mechanism be notoperated at all. VVehave shown the following devices for preventing theo eration of the printing mechanism in that case. As shown, it consistsof the following devices: 90 is a finger mounted on sleeve 289.

Sleeve 289 is mounted with shaft 89 by means of spring9l connected toboth parts. Ordinarily the movement of shaft 89 will rotate sleeve 289and move finger 90 ,up-

ward until it comes into contact with-the,

under side of the card, as shownin Fig. 11L

This takes place just before cam 99 comes:- lf a card has shown in Fig.11, cam 100 does not strike or interfere with the action of trip 94 and.

the-printing is effected as already described. If no card, however, wasinserted 1n the slot or is not inserted far enough back finger 90 willcontinue its movement as shown in Fig. 12 bringing cam 100- under andinto contact with the pawlflend of trip94 and .96 to efiect theoperation of the parts as described. In the above way the printinghammers are not retracted unless a card is inmost limits printing can beprevented ex.

The inking ribbon mechanism is illustrated in Figs. 3, 4,-7 and 8-. -Anysuitable inking ribbon fed mechanism may be employed. That shownconsists of an arm 46 fast on the sleeve of. crank arm" 68, alreadydescribed, and provided with a link 44 connect-ing it with link 294carrying pawl 43 in the usual manner, the latter engaging with a ratchet42 fast on shaft 69 which carries at one end acrown gear 39 adapted tomesh with a similar gear 39 on shaft 41. Shaft 69 is provided at itsother end with a similar gear meshing'with gear 40 on -'a similar shaft41. It also has an impositive lock 45 for holding it in either position.

As shown, the left hand gear'on shaft 69 is.

in mesh with gear 40 and out of mesh with As shown the inking ribbon 295is being fed to the left as viewed in Fig. 4 at each operation of thehandle. Any suitable, means may be provided for reversing the directionof feed. That shown consists of a clutch arm 37 working in groove 38 onshaft 69. The inking ribbon is provided with a button at either end, one

of which,293 at one end'only is shown. 31

and 32 are two rocking arms mounted at 35 and 36 and connected by link27. Onarm 32 is a roller 33 engaging one or the other of two slopingsurfaces on the end of spring arm 34. When button 293 strikes arm 32 andforces it to the left, as viewed in Fig. 4, roller 33 rides up thesloping surface of spring arm 34-causing clutch 37 to'j'erk to the rightto throw shaft 69 toxthe'right causing crown gears 39 to meshandseparating crown gears 40 and also causing the impositive spring to jumpinto the adjoining groove... The feed is now in the opposite direction.similar operation takes place when the ribbon reaches the other extremelimit of its movement. Spring 296' provided with the adjusting nut 297are ordinary means for giving tension.

UZoal-c mechanism and driving years.- These are especially illustratedin Figs. 2, 3 and 4. Any suitableform of clock movementanddr'ivingconnections for operating the clock disk cams may be employed.The clock movement may, if desired, be made powerful enough to drive anyor allwof the different parts of the mechanism of our im- 7 We prefer,however, to

clock movement may be employed and the clock movement itself is therebymade more accurate and reliable. In the particular form of ourimprovement shown in the drawings the clock movement drives nothing butthe various stop cams. This work is very light and requires but littlepower.

The particular devices shown consist of a clock work 7 which may be ofany desired construction. As shown, it is connected by a flexible shaft298 carrying bevel gear 300 meshing with bevelgear 301 on shaft 302.East on shaft 302 is gear 50 which rotates once an hour and which mesheswith gear 1.56 already described. This operates the minute stop cams.The hour stop cams are operated by a train of reducing gears 51, 52', 53and 55. Gears 52 and 53 are fast on shaft 53. Gear 55 rotates once intwenty-four hours and meshes with the hour stop cams. The handle andvarious parts of the mechanism are returned to their normal or originalpositio-n'by means of spring -102 connected to the side frame of themachine and the crank arm 10% on shaft 89.

30a and 305 are springs secured to the frame work and to hell cranks 62and 61 respectively for returning the bell cranks and connecting partsto their original positions when permitted by cams .66 and 65.

The type wheels and connecting parts normally are returned to theirpositions at the last instant of the upward movement of handle 5 bycrank arm 46 striking wire 47 secured to shaft 49 lifting the two pawls43 out of engagement with the ratchets 12 and 13. This permits the typewheels and their connecting gearing to return to their zero or originalposition. In the position of the machine at rest the pawls as are heldout of engagement with ratchets 12 and 13. They are thrown intoengagement at the very first operation of the handle being pulled downby springs the moment crank arm 46 permits.

The selecting fingers are returned to their original position by thereturn of the links 70 and 71 causing the drivlng arms and blocks to goback forcing the driven blocks and selecting fingers to return to theiroriginal position.

306 is a sloping. surface (see Fig. 3) formed in the fran'ieworksurrounding the slot on the left. The object is to cause the selectinglingers 133 and 13st to strike the sloping surface and be forceddownward and out .f the path of the card in the slot. Qtherwise in themachine shown it would impossible to insert a card into the slot.

The subtractor cams 220 are restored to their normal or inoperativeposition as already described above by slight rebound of shaft 2l t'tothe right as viewed in Fig.

This is accomplished. by cam striking hell crank 73 (Fig. 5) moving theother arm of the bell crank to the right as viewed in Fig. 5 against thespring 76 pulling rod 77 to the right. Rod 77 is secured to arm 306(Fig. 5) on rock shaft 214. The purpose of spring 76 is to make aflexible connection between 74 and the parts it drives so that if cams220 are in their down position the spring will take up the movement.This is accomplished by causing rod 77 to pass through an opening in arm74: and placing spring 76 between the arm 74: and a head secured at theright end of rod 77 so that the pressure exerted on rod 77 passesthrough the spring.

It is evident that, as the clock stop cams are driven continuously bythe clock movement, they will be driven during lunch hour and at othertimes when the.

operator is not working and a record is not deslred. If. desired, adevice may be employed for stopping the operation of the clock stop camsduring such interval. Any devices may be'employed for this purpose. InFigs. 26 and 27 we Show our preferred form for accomplishing thispurpose. In these devices the clock movement and the clock stop cams areoperatively disconnected, as for example, during the lunch hour. Theparticular devices shown for the purpose consist of the following Ongear 229 is mounted a cam 307 adapted to engage a pin 308 on an arm 225pivoted at 309 ina bracket in the frame work 230 and carrying at itsother end a pawl 226 engaging ratchet 227 mounted on a shaft 228 mountedloosely in the frame work and carrying with it a disk 233 provided withtwo cam surfaces 234. Of course any number of cams can be mounted onthis disk to suit the circumstances of the case. 231 is an arm pivotedat 311 and normally pressed byspring 310 so that its nose rests againstdisk 233, which is secured to a sleeve'on shaft 302 carrying onememberof a clutch 232. As earn 307 turns once every hour disk 233 is fedforward one point at the end of each hour. When a cam surface 23% comesopposite the nose on arm 231 it separates the clutch faces, thusseparating the clock movement from the clock stop cams. he latter remainat rest so long as cam 234.- is in contact with the nose on arm 231, Byproperly proportioning cams 234 and 307 any interval of time desired maybe subtracted. By varying the position of cams 23% on disk 233 theintervals subtracted may occur at any time during the day or night.Where such stopping devices are employed we preferably employ a cardwithout a scale, as shown in Fig. 24. If desired a scale may be employedbut in that case the time, during which the clock cams are disconnectedfrom the clock movement, must also be omitted from the scale, or thelatter will not correctly represent the starting time.
